When the DERM's were ordered matching trailers were also ordered. However oddly there was half as many trailers as there were railmmotors. Currently one is preserved at the Daylesford Spa Country Railway and 28MT was sighted in a property in Dandenong in 1998. The status of the dandenong one is unknown at this stage since the property was cleared for a road development and the trailer 'went missing. 30MT has also been reported as being on a property near Echuca. When withdrawn only 26MT was preserved while the other 4 were sold off. Only 28 and 30 have been located since withdrawal.
